Reheating of steam in a turbine

WebReheating is applied in a gas turbine in such a way that it increases the turbine work without increasing the compressor work or melting the turbine materials. When a gas turbine plant has a high pressure and low pressure turbine a reheater can be applied successfully. Reheating can improve efficiency up to 3%. WebNon-reheat turbines are the solution which best suits the needs of industrial plants and small utilities. The Ansaldo Energia non-reheat steam turbines portfolio includes machines from one to three cylinders, capable of covering a wide range of steam cycles, site conditions and operating modes. For small ratings, a compact single cylinder machine, …

Web7 Steam at 10 MPa, 6008C enters the first-stage turbine of an ideal Rankine cycle with reheat. The steam leaving the reheat section of the steam generator is at 5008C, and the condenser pressure is 6 kPa. If the quality at the exit of the second-stage turbine is 90%, determine the cycle thermal efficiency. We have an Answer from Expert. WebSteam at 7 is reheated in the reheat section (RH) to a higher temperature at 8 where steam expands further in the intermediate-pressure steam turbine (IPST) to the low pressure at 10.

WebReheat steam turbines increase efficiency by returning partially-expanded steam to the steam generator for reheating before feeding it back to the turbine. The Ansaldo Energia … WebA hypothetical steam power plant operates on an ideal Rankine cycle with reheating. Steam enters the high pressure turbine at 8 MPa and 500 C and leaves at 3 MPa to enter the isobaric reheater. After reheating, the steam at 500 C then enters the low-pressure turbine and expands until 20 KPA to go to the condenser. Determine the turbine specific ...
